Abstract:
A research project was carried out to validate the target compounds that lead to customers’ complaints about interior cabin odor. The goal was to understand what the threshold sensitivity of the customer might be, in order to determine where to set internal targets for customer satisfaction. Compounds called out by the GB/T27630-2011 and TUV Rheinland Toxproof standards that have odor descriptions, odor thresholds and irritation levels were studied, and a design of experiments (DOE) was conducted. Acetaldehyde, toluene, acetone and butyraldehyde were used to conduct the odor study by reconstituting their concentration in vehicles. It is concluded that aromatics, aldehydes, and ketones have a direct relationship to odor concerns.
